Abstract

L'invention concerne un système à ressort pneumatique destiné à supporter des suspensions ou des essieux sur une caisse de véhicule. Ce système comporte une membrane roulante tubulaire placée entre une fixation de support de roue ou de guidage de roue et une fixation côté caisse du véhicule, laquelle membrane est montée entre un élément de support et un piston de déroulage pourvu d'une cavité résistante à la pression, ledit élément de support et ledit piston de déroulage étant guidés l'un sur l'autre par l'intermédiaire d'une articulation coulissante centrale. A cet effet, un tube de commande est placé sur l'élément de support. Ledit tube de commande est en partie évidé au niveau de sa surface extérieure et présente des moulures ou des ouvertures pour canaux. La cavité du piston de déroulage présente un collier de commande qui entoure avec un jeu le tube de commande au moins dans la zone correspondant à la course et recouvre entièrement ou partiellement la zone évidée, les moulures ou les ouvertures, en fonction de la course de débattement. La présente invention permet d'obtenir un système à ressort pneumatique pourvu d'un déplaceur modifiant son volume gazeux, de manière simple, en fonction de la course de débattement.
